Methods for preparing autologous blood eye drops

ABSTRACT

A convenience kit for sterilizing and delivering liquids into the safety of a sterile environment inside a plastic bag (which can be disposed in a field environment) wherein a so sterilized liquid is dispensed into a vessel which is capped and sealed before removal from the bag. The convenience kit can be provided in a solitary format or, as a subkit combined with other associated items in a more inclusive convenience kit. In short, convenience kits made according to the present invention provide opportunity for accomplishing an aseptic liquid sterilizing transfer, a task which is commonly associated with on-hand capability of a laminar flow hood, in field environments and other areas which are remote from facilities having laminar flow hoods.

FIELD OF INVENTION

This invention relates generally to devices for medical proceduresinvolving liquid transfer, sterilization and mixing in a fieldenvironment. It is also particularly related to kits and to methodswhich employ preassembled parts to provide a sterile product withoutrequiring confines of a laminar flow hood.

BACKGROUND AND DESCRIPTION OF RELATED ART

Conventionally, mixing and formulation of medications is a pharmacy orother medical laboratory performed function most often involving use oflaminar flow hoods and strict aseptic tehcnique to maintain sterility.In pharmacies, medical solutions are often passed through a medicalgrade sterilizing filter to assure an aseptic condition. Resultingproducts from these facilities are highly regarded and widely used inhospitals and other clinical facilities.

However, today, a significant portion of medical practice takes placeoutside sophisticated medical institutions. As an example, a new andvery effective eye-wash technology is based upon mixing autologous bloodserum with normal saline in exacting proportions. Commonly, blood isdrawn from patients in a wide range of areas remote from pharmacies andlaboratories. The expense and inconvenience of relying on suchfacilities to sterilize and mix is prohibitive, negatively affectingbroader application of this promising technology. Thus, there exists asevere contemporary need for a process or methodology, not currentlyavailable commercially, which can, with appropriate safety and efficacy,provide such sterilizing, dispensing and mixing in a field environment.

Convenience kits have become commonly used appliances for a number ofreasons. First, a convenience kit is specifically made for a givenapplication. Contents of each such kits are prepared and provided in aform which generally reduces procedure steps and improves efficiency.Second, such kits can provide additional safety such as the kitdisclosed in U.S. Pat. No. 9,449,521, titled METHODS FOR MAKING ANDUSING A VIAL SHIELDING CONVENIENCE KIT, issued May 28, 2013, whichproved effective in providing additional safety to technicians andpatients by keeping hazardous drug fumes and liquid fully contained.

BRIEF SUMMARY AND OBJECTS OF THE INVENTION

In brief summary, this novel invention alleviates all of the knownproblems related to mixing, dispensing and providing a sterile liquidproduct in a field environment.

Commonly, such products, as disclosed supra, are often produced by beingsterilized by filtration and mixed under a fume or laminar flow hood ina pharmacy or laboratory facilities. For products which are acquired forsterilizing and mixing in a field environment, remote from suchfacilities, lack of a fume hood or laminar flow capability currentlyprohibits wide-spread manufacturing It is for the purpose of fulfillingthis need that a convenience kit based upon the instant invention isintended.

The core items of this inventive kit are a conventional commercialplastic bag, having an accessible opening, which is closed and sealedafter product assembly, and a sterilizing filter component which isaffixed to the bag via a sealed portal to provide a solitary sterilizingfluid pathway to other components inside the so closed bag. To assureproduct sterility, the bag and contained articles are sterilized afterassembly prior to use. Once sterilized, the only passageway inside thesealed bag is through the filter component. Therefore, all productinside the bag remains sterile for all subsequent procedures until thebag is opened.

The inventive kit may be delivered as a constituent of a larger, moreinclusive kit comprising additional items for a particular procedure. Insuch a case, the inventive kit is part of the larger kit and isreferenced as a subkit. As is clearly disclosed hereafter, otherproducts delivered in the inclusive kit should be clean, but need not besterilized before use with the inventive kit.

An example of components of a kit made according to the presentinvention may be as follows:

1. The plastic bag having an accessible opening for displacement of thearticles into the bag before the opening is closed and sealed and anexterior surface which completely envelopes and protects sterility ofarticles disposed therein. Bag and articles disposed therein should bepredisposed to digital manipulation via the bag exterior.

2. A filter component comprising a sterilizing grade filter and twoopposing elongated conduits having connecting fittings at ends remotefrom the filter. One of the conduits, is displaced through a hole in thebag. A gasket seal is disposed about the conduit/hole interface,providing a hollow conduit as the only fluid access pathway into the bagafter the bag opening is sealed. Note that the pathway leads to thefilter through which all fluid must pass, thereby assuring that nonon-sterile material can be introduced into the bag beyond the filter.

3. At least one vessel for receipt of dispensed liquids.

4. A cap for each at least one vessel, the cap being affixable andproviding a protective seal, such that when attached to the vessel andthereafter removed from the bag, following liquid transfer, productsterility is assured.

5. A receptacle for holding each at least one vessel and associated capin a preferred accessible position and state. (Optional)

6. A basin wherein wasted priming (waste) liquid can be delivered.(Optional)

One of the compelling purposes for basic convenience kits resulting fromthis invention is providing fluid flow through an associated sterilizingfilter. As liquids to be mixed in a field environment can be expected tobe compromised and/or contaminated, it is critical that everyso-employed liquid is passed through such a filter and sterilized beforebeing dispensed within the bag. In the case of the instant invention,retention of sterility throughout dispensing and mixing is equally asimportant. For this reason, all kit mixing, sterilization and subsequentpackaging functions are performed within a plastic bag which retainssuch sterility until reopened. It is important to note that digitalfacility of kit use is also very important. As a consequence, finalproduct is not removed from the bag until capped and sealed for safetransport in the field environment. Note that this requires productdispensing and capping take place within the bag.

As well as providing for field sterilization and mixing, a conveniencekit according to the present invention, may be a sub-kit supplied in amore inclusive kit format, comprising parts supplied unpackaged withinthe confines of a kit container, for saving time and steps. Additionaltime may be saved by unitizing assembly of functional parts of the kit.For example, those sub-kit components which are not separated as part ofthe procedure are securely affixed as a unit (unitized), one to another(such as by adhesion). As an example, a fluid delivery spout can besecurely affixed to an output conduit of a filter component internal tothe bag and a fluid delivery control unit may be affixed to an inputconduit of the filter. In this manner, sub-kit components are providedto a handler in a “ready to use” format which is inherentlyincorruptible.

Inclusive kits, based upon the present invention, may have a variety ofcomponents disposed within a transport tray. While such components anditems can be selected and fixed for each particular application, a widediversity of parts may be used for both components and items within thescope of the invention. However, in all cases, components are generallyaffixed one to another, as necessary, to provide a “ready to use”configuration. Also, if gamma radiation is used for sterilization, onlyradiation stable components should reside within the bag of theinventive kit.

As disclosed hereafter, various convenience kit configurations may beused for sterilizing, transferring and mixing, as the filter componentpermits a wide range of sterilizing applications that fit within a bag.Other application examples for the instant invention includes batchfilling of antibiotic and operating room syringe kit applications,oncology drug dispensing, short half-life drug delivery and kits forhome care.

Further, to show by example, a comparison of advantages anddisadvantages relative to using a convenience kit made according to thepresent invention versus using a laminar flow hood, for a steriletransfer process, distinctions are summarized in the following twotables (i.e Tables 1 & 2).

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

In this description, the term proximal is used to indicate a segment ofa device normally closest to an object of the sentence describing itsposition. The term distal refers a segment oppositely disposed.Reference is now made to the embodiments illustrated in FIGS. 1-13wherein like numerals are used to designate like parts throughout. Forparts which are similar but not the same as parts originally specifiedwith a given number, a prime of the original numbers is used.

While kits made according to the invention may be configured to provideassemblies for many medical procedures, such as those, for example,involved with sterile washes and drugs for home-care, antibiotics,operating room and pediatrics, disclosure of an exemplary application inthe area of preparation of a specialized eye-wash is herein selected toprovide examples and details of the instant invention while clearlydemonstrating critically important safety and time and work savingfeatures.

Reference is now made to FIG. 1 wherein significant components of aconvenience kit 10 made according to the instant invention are seen. Thecomponents are:

a. a sterilizing filter component 20 comprising a filter casing 22, twoelongated fluid communicating conduits with luer fittings on an enddisposed away from filter component 20, (i.e. a first conduit 24comprising a female luer fitting 26 and a second conduit 28 with a maleluer fitting 30). A filter (not shown) is disposed within filtercomponent 20, through which all fluid displaced through the conduits 24and 28 must pass. The filter is a medical grade sterilizing filter whichis defined to be on the order of a 0.2 micron filter rating. Filtercomponent 20 should have a substantially planar face 32 for interfacingwith a portion of the exterior surface of an associated plastic bag.Such a filter is currently available commercially as a Merck MilliporeMILLEXGS Sterilizing Filter unit.

b. a pliant, preferably clear plastic bag 40 comprising a continuoussurface 42 and a single opening 44 which is heat sealable. Such a bag isfound commercially in many forms. As an example, a 1.4 mil polyleak-proof, heat sealable bag is currently preferred. The selected bagshould be sized to permit digital access to contents within the bag.Such bags can be perforated by a sharp object such as a common pin at adesired perforation site (in this example, site 50). Note that site 50can be determined to be any desired place on the surface of bag 40 whichpermits desired digital maneuvering of filter component 20. At such aperforation, material characteristics of the bag permit displacement ofa conduit part through the point of perforation with only an increase inhole size equivalent to circumference of the perforating member (i.e. inthis case, filter conduit 28).

c. three components which can be used to seal the perforated hole atsite 50.

-   -   The first component 60 is preferably a section of tube stock        which is elastic, pliant, and incompressible having an internal        diameter which tightly fits about conduit 28 adjacent filter        casing 22 and preferably has an external diameter 66 (see FIG.        1A) which provides a ⅛ inch cushion about conduit 28 and a        length 64. An example of such tube stock is silicone tubing.    -   The second component 70 performs as a nozzle extension for        conduit 28 and preferably comprises a female luer fitting 72        comprising side flanges 74 which are designed to be luer-lock        latches. Fitting 70 can be a conventional male/female luer-lock        fitting. Component 70 also preferably has a pair of rigid side        wings 76.    -   The third component 80 is a washer shaped component which is        sized to communicate with fitting 72 flanges 74 and a proximal        surface of component 60. Component 80 should be sufficiently        rigid to retain a planar form when disposed to communicate        connective forces between fitting 72 and tubing component 60 to        thereby provide gasket support.    -   Note that component 60 (being and interface gasket) when used as        a gasket part is disposed about conduit 28 between flanges 74        and face 32. Component 60 should be a section of tubing having a        length, as cut, which is sufficiently greater than the distance        between flanges 74, and face 32 of filter component 20 to        provide force forming a fluid tight seal against bag 40 interior        surface in contact with planar face 32, but short enough to not        generate a force sufficient to disengage component 70 from        conduit 28.

A filter to bag fabrication tool 90 is seen to provide a walled hole 92which has a pair of slots (not shown) disposed to fit about side wings76 to retard component 70 from rotating as component 70 is securelyaffixed to conduit 28 (by conventional luer fitting attachmenttechnique). Assembly process is as follows:

-   -   Components 60, 80 and 70 and tool 90 are disposed within bag 40.        Component 70 is displaced into hole 92 such that wings 76 are        retarded from rotating. Bag surface 42 is pierced at site 50        providing a pin sized hole. Conduit 28 is forcefully displaced        through bag surface 42 at site 50. Component 60 is displaced        about conduit 28. Component 80 is next displaced about conduit        28 in contact with component 60. Then, making a luer connection,        component 70 is securely affixed to conduit 28. It is preferable        that an adhesive is disposed to interface between connecting        surfaces of conduit 28 and component 70 to assure long term        product stability. Tool 90 is displaced from bag 40.

In FIG. 2, an assembled combination is seen showing filter component 20affixed through a closed and sealed hole to bag 40 (showing female luerfitting 26 disposed outside bag 40) and components 60,80 and 70 linearlydisposed within bag 40. Only a segment 94 of bag 40 is seen for clarityof presentation.

Attention is now referenced to FIGS. 3, 4 and 5 wherein components of aset for producing a sterile eye-wash product are seen. In FIG. 3, astabilizing tray 100 is seen to comprise a series of cavities, generallynumbered 102, each of which has a specific purpose as disclosedhereafter. Tray 100 may be made of polystyrene or other rigid plasticwhich is radiation stable. Vacuum or other molding methods may beemployed to fabricate tray 100. In this example, cavities 102 which arededicated to eye-wash receiving vessels are also numbered 104. Cavities102 which are dedicated to caps for the vessels are numbered 106. Asingle cavity 108 is centrally disposed and has multiple functions, oneof which is acting as a reservoir for receipt of priming residue.

A vessel 110 for receiving and storing eyewash is seen in FIG. 4. Asvessel 110 is used for dispensing eye drops it should be fabricated offlexible material which is radiation stable. Vessel 110 comprises athreaded, superiorly disposed wall 112 about an opening 114.

A sealing and protective cap 120 for vessel 110 is seen in FIG. 5.

Cavities 106 are sized and shaped to securely, but release-ably, retaincaps 120 therein, as seen in FIG. 6. Cavities 104 are sized and shapedto securely, but release-ably, retain vessels 110. The combination of atray 100 laden with caps 106 and vessels 104 is referenced as filledtray 130 hereafter.

A first step in convenience kit assembly is displacing a filled tray 130(see FIG. 6) into bag 40 through opening 44 (see FIG. 1) as seen in FIG.7. After the tray is so disposed, bag opening 40, as a second step, isclosed and sealed (forming closed opening 44′) as also seen in FIG. 7.Note that conduit 28 can be disposed in cavity 108 for packaging andstoring purposes.

A third and final assembly step for providing a ready to use conveniencekit 200 (seen in FIG. 8) is sterilization. While other modes ofsterilization can be used, it is preferred to use gamma radiation whensterilizing to provide kit 200. For this reason, all parts andcomponents used to fabricate kit 200 should be radiation stable. Itshould be noted that, once sterilized, all contents of convenience kit200 cannot be further contaminated or de-sterilized as all matter andfluid which can enter bag 40 must enter through filter component 20which inhibits contaminated matter and sterilizes all fluid displacedthere through. (Note that, unless stated differently, reference to beingsterilized generally implies being sterilized to a predetermined SAL,hereafter.)

Thus, unless either the bag or filter barrier is perforated or rupturedall matter within the walls of bag 40 shall remain in an aseptic state.This permits dispensing fluids from an uncontrolled and potentiallycontaminating environment to be performed without regard to conditionsexterior to kit 200.

For this reason, kit 200 may be considered superior to performance ofthe same function using a laminar flow hood. For, while the laminar flowhood provides an aseptic flowing gas-based environment, generalachievement of an aseptic product requires careful technique andseparate procedures to assure product sterility (as there is no facilitywhich is part of a laminar flow hood, itself, which inherentlysterilizes a product being produced therein).

As seen in FIG. 8, Female luer fitting 26 of filter component 20 of kit200 is readily accessible for use in dispensing, through filtercomponent, liquids into vessels within kit 200. As seen in FIG. 9, aconventional medical syringe can be affixed to fitting 26. So attached,syringe 210 may be displaced to lift or “tent” portions of bag 40 toprovide a more facile access to components disposed within kit 200.Also, with or without syringe 210, filter component 20 may be sodisplaced to permit gas to enter bag 40 (being sterilized thereby) toestablish more access space. However, once liquid has been delivered tothe filter, the filter is wetted and blocks further transmission of gasthere through.

As seen in FIG. 9, a so-attached syringe 210, or other luer fittingattached instrument, can be used to dispense liquid into a selectedvessel 104 or cavity 108 (in the case of priming). All liquid, sodispensed, is sterilized by passage through filter component 20 suchthat all items and surfaces inside bag 40 remain sterile. Syringe 210 isseen to be superiorly disposed relative to a selected vessel 104 fordispensing sterilized liquid therein in FIG. 10.

Once filled each vessel must be capped to preserve sterilized productbefore the bag is opened to the field environment. The bag should besized and bag material selected which permits a digital interfacebetween cap and a users thumb and fingers to permit a cap 120 to bedisengaged from a cavity 106 and displaced and be affixed to cap andseal product within a vessel 110. Sealing may involve rotating a cap,like cap 120, by threaded attachment as evidenced by vessel wall 112(see FIG. 4). Depending upon cap material and frictional interfacebetween bag 40 and cap 120, grasping and twisting a cap within bag 40may be challenging. To provide an improved frictional interface, a cap120 side attachment, such as a rubber band 220 seen in FIG. 9 can beused to provide assistance.

Due to associated functional requirements of a procedure involving thepresent invention, sterilized kit 200, may become a subkit if added to amore inclusive storage and shipment kit tray 230, as seen in FIG. 11. Insuch a case, it is preferred that other items provided within a tray230, generally numbered 240, be compartmentalized as seen in FIG. 11.

It is preferred to provide a cover 240 which is sealingly affixed totray 230 to protect product cleanliness as seen in FIG. 12. Note thatsterility protection is not required as kit 200 is a fluid sterilizingas well as an aseptic protecting instrument. Therefore, cover 240 may beremoved from tray 230 for kit component access with safety in a fieldenvironment. Also, as may be noted in FIG. 12, removing cover 240 canprovide a clean work area on the underside 242 of cover 240.

As indicated supra, convenience kits, made according to the presentinvention, may be used for transferring and sterilizing liquids in manyapplications. To provide a broadened perception of uses of suchconvenience kits, a second example is seen in FIG. 13.

Therein, a syringe 300 is sealed within a bag 40′ and sterilized withother components inside to provide a convenience kit 200′. A filtercomponent 20 affixed to bag 40′ at a site different from site 50 (site50′) provides a sterilizing fluid pathway into bag 40′. Thereat,component 20 is affixed to bag 40′ by the same process and manner ascomponent 20 and components 60, 80 and 70 are affixed to bag 40. In use,all liquid dispensed through filter component 20 is sterilized beforereaching pre-sterilized syringe 300. Syringe 300, being so filled, isdigitally detached and a conventional luer cap 302 is digitally affixedthereto to provide a sterile liquid product for use in the fieldenvironment. In this manner, such a kit can be used to transferquestionable or contaminated liquid from a container (e.g. anothersyringe) to be sterilized and further dispatched to syringe 300 fordelivery of a sterile product to a patient in the field environment.

The invention may be embodied in many other specific forms withoutdeparting from the spirit or essential characteristics thereof. Thepresently disclosed embodiments are therefore to be considered in allrespects as illustrative and not restrictive, the scope of the inventionbeing indicated by the appended claims rather than by the foregoingdescription, and all changes which come within the meaning and range ofequivalency of the claims are therefore intended to be embraced therein.
